Re: [Plplot-general] changing plot labels

[Alan W. I. <ir...@be...>]

Look at
http://plplot.org/resources/docbook-manual/plplotdoc-html-0.4.1/annotation.html
where the tradeoffs between fixed and floating point labelling are
extensively discussed. Also follow the links to plprec, plsxax, plsyax, and
plszax.

These routines should give your users complete control over whether fixed
or floating point is used in their labels.

Fixed or floating point labels are often a matter of taste, so I will be
reluctant to make any large changes in the default decision (which can be
overridden as above) since a default satisfying one group of users might
piss off another group.

However, last year I did go through the code to refine the fixed versus
floating point labelling decision as much as possible so the new results
were in a small minority of cases that I tested not identical to those from
an older snapshot.  But with the new code the possibility of making a
nonsensical default decision is now reduced considerably.  (For example, the
old code did not properly account for the space taken up by the negative
sign on a label if the data range included both positive and negative
numbers.) Of course, be sure to send in a report if you find any bugs in the
current code for this fixed versus floating point labelling decision.
